Brush-On Fabrication of Suspended PLLA-PEO-PLLA Triblock Copolymer Fibers
Parallel fibers can be rapidly created by manually brushing solvated polymer solutions over arrays of microfabricated pillars. Recently, this technique has been utilized to produce suspended arrays of micron and sub-micron scale fibers consisting of a new triblock copolymer composed of a hydrophilic mid-block of polyethylene oxide (PEO) surrounded by two hydrophobic end groups of poly-L-lactic ...
متن کاملNew slant on photonic crystal fibers
We present the novel use of microstructured optical fibers not as “light-pipes”, but in a transverse geometry to manipulate the light propagating across the fiber. Fundamental and higher-order bandgaps were observed experimentally in this geometry using a number of techniques. The comparison of the measured spectra with photonic band structure and Finite-Difference Time-Domain simulations provi...
متن کاملTao Brush.
The Tao brush is a small flexible brush used in TruTest Endometrial Biopsy. Endometrial tissue to a depth of 1.5–2 mm can be collected. It gently brushes the entire inside of the uterus so as to gather a more complete sampling of the endometrium and is less painful than the traditional method [1]. It covers a wide area of the endometrial surface. Therefore, small lesions are less likely to be m...
متن کاملGum Tragacanth Fibers Introducing Primitive GT Fibers (RESEARCH NOTE)
In this research, a method for producing gum tragacanth (GT) fibers is presented. Ribbon type GT of Astragalus Gummifer species were obtained from local production lands. The gum was treated with alkali to increase its process ability, and allowed to stand for a period of time to reach the proper viscosity and/or to "ripen". Samples with different ripening times were prepared and their viscosit...
متن کاملFABRICATION OF CARBON FIBERS FROM COMMERCIAL WET SPIN POLYACRYLONITRILE FIBERS
Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...
